Text Solution
AI Generated Solution
The correct Answer is:
### Step-by-Step Solution:
**Step 1: Understand the Assertion and Reason**
- The assertion states that "Rayon is a semisynthetic polymer and is taken as a better choice than cotton fabric."
- The reason states that "Mechanical and aesthetic properties of cellulose can be improved by acetylation."
**Step 2: Analyze the Assertion**
- Rayon is indeed classified as a semisynthetic polymer. It is derived from natural cellulose, which is obtained from wood pulp.
- The process of making rayon involves chemical treatment of cellulose, making it semisynthetic.
- Rayon is often considered a better choice than cotton fabric due to its improved properties such as softness, luster, and drape.
**Step 3: Analyze the Reason**
- The reason mentions that the mechanical and aesthetic properties of cellulose can be improved by acetylation.
- Acetylation is a chemical reaction where cellulose is treated with acetic anhydride, enhancing its properties. This process results in rayon, which has better qualities than untreated cellulose.
**Step 4: Determine the Relationship Between Assertion and Reason**
- Both the assertion and reason are correct statements.
- The reason explains why rayon is considered a better choice than cotton, as the acetylation process improves the properties of cellulose, leading to the creation of rayon.
**Step 5: Choose the Correct Option**
- Since both the assertion and reason are correct and the reason explains the assertion, the correct option is:
- **Option 2:** Assertion and reason both are correct statements and reason explains the assertion.
### Step-by-Step Solution:
**Step 1: Understand the Assertion and Reason**
- The assertion states that "Rayon is a semisynthetic polymer and is taken as a better choice than cotton fabric."
- The reason states that "Mechanical and aesthetic properties of cellulose can be improved by acetylation."
**Step 2: Analyze the Assertion**
- Rayon is indeed classified as a semisynthetic polymer. It is derived from natural cellulose, which is obtained from wood pulp.

It is often said that India has got the third largest pool of scientific and technological manpower in the world. The harsh truth is that except for a few selected areas, breakthrough in technology including drive for indigenisation have met with limited success. There are neither adequate resources nor proper support to carry out fundamental research, development of indigenous technology or commercialisation of new technology by the Indian industries. The choice of technology and its source is an important aspect as it relates to quality and price of technology. The actual goal of transfer of technology is the establishment of scientific and technological capabilities rather than the mere transfer of plant and equipment. Technology transfer consists of three major components, technology assessment, technology acquisition and assimilation and technology diffusion to local industries after incorporating the necessary degree of modifications. Organisation may lack the professional skills to select a technology thatis suited to local operating conditions and to acquire it on favourable terms. They are guided by past relations, current affiliations and terms and conditions set in the aid package. Thus the technology transfer process becomes often too costly and ineffective. The technologies, which are latest in the field are usually non negotiable and least available for acquisition. Unless the importing organisation ensures the availability of qualified personnel and resources, the technology transfer is bound to suffer or may prove ineffective. Technology transfer could be a multi-edged weapon which, if handled wrongly, may result in expensive/ unwanted imports, hurting the technological progress and ultimately may lead to disaster. Interaction between industry, engineering consultancy organisation, R&D centres and academic institutions is very limited. Industrial/ engineering consultants have limitations of time. By the time a technology is developed, it becomes very costly and sometimes outdated. Due to this reason, industry/engineering consultants have a tendency to avoid academic institutions and R&D centres. As academic institutions and R&D centres do not receive due attention of industries, they prefer working in isolation. The fact remains that the acadernics who do not understand the corporate .world cannot survive and the corporate world that does not use good academic input can't grow. There has to be a mutual appreciation instead of competing, they should complement each other. Indigenisation:
