If 50 glucose molecules combine to form ‘A’ polysaccharide. The general formula of ‘A’ polysaccharide will be
(a) `C_(300)H_(600)O_(300)`
(b) `C_(300)H_(500)O_(250)`
(c) `C_(300)H_(502)O_(250)`
(d) `C_(250)H_(500)O_(250)`

Options

A. `C_(300)H_(600)O_(300)`
B. `C_(300)H_(500)O_(250)`
C. `C_(300)H_(502)O_(250)`
D. `C_(250)H_(500)O_(250)`

Answer

To solve the problem of determining the general formula of the polysaccharide formed by the combination of 50 glucose molecules, we can follow these steps:

### Step 1: Identify the molecular formula of glucose
The molecular formula of glucose is \( C_6H_{12}O_6 \).

### Step 2: Calculate the total number of carbon, hydrogen, and oxygen atoms from 50 glucose molecules
Since there are 50 glucose molecules, we will multiply the number of each atom in one glucose molecule by 50.

- **Carbon (C)**:
\[ 6 \text{ (from one glucose)} \times 50 = 300 \text{ (total carbon)} \]

- **Hydrogen (H)**:
\[ 12 \text{ (from one glucose)} \times 50 = 600 \text{ (total hydrogen)} \]

- **Oxygen (O)**:
\[ 6 \text{ (from one glucose)} \times 50 = 300 \text{ (total oxygen)} \]

### Step 3: Write the preliminary formula
From the calculations, the preliminary formula for the polysaccharide formed by 50 glucose molecules is:
\[ C_{300}H_{600}O_{300} \]

### Step 4: Identify the correct option
Now, we need to compare our derived formula with the options given in the question:
- (a) \( C_{300}H_{600}O_{300} \)
- (b) \( C_{300}H_{500}O_{250} \)
- (c) \( C_{300}H_{502}O_{250} \)
- (d) \( C_{250}H_{500}O_{250} \)

The correct option that matches our derived formula is:
**(a) \( C_{300}H_{600}O_{300} \)**

### Final Answer:
The general formula of the polysaccharide 'A' formed by the combination of 50 glucose molecules is:
**(a) \( C_{300}H_{600}O_{300} \)**
