Answer

To answer the question regarding heroin, we need to fill in the blanks with the correct chemical name and the process by which it is obtained from morphine. Let's break it down step by step:

### Step 1: Identify the Chemical Name of Heroin
Heroin is commonly referred to as "smack." The chemical name for heroin is **diacetylmorphine**. This is the first part of the answer.

### Step 2: Describe the Physical Properties of Heroin
Heroin is described as a **white, odorless, bitter crystalline compound**. This describes its appearance and taste.

### Step 3: Determine the Process of Obtaining Heroin from Morphine
Heroin is synthesized from morphine through a specific chemical process. The correct process is **acetylation**. This means that an acetyl group is added to morphine to produce diacetylmorphine (heroin).

### Final Answer
Thus, the complete answer to the question is:
Heroin, commonly called smack, is chemically **diacetylmorphine**, which is a white, odorless, bitter crystalline compound obtained by **acetylation** of morphine.
