For molecular formula `C_( 4) H_(9) NO` how may amide will be there which will not form H --bon ? (only structural )

Explanation

To solve the problem of how many amides can be formed from the molecular formula C₄H₉NO that do not form hydrogen bonds, we can follow these steps:

### Step 1: Understand Amides
Amides are compounds that contain a carbonyl group (C=O) directly attached to a nitrogen atom (N). The general structure of an amide is R-C(=O)-N-H₂, where R can be a hydrogen or an alkyl group.

### Step 2: Identify Degrees of Amides
Amides can be classified based on the number of hydrogen atoms attached to the nitrogen:
- **Primary Amide (1°)**: R-C(=O)-NH₂ (1 hydrogen attached to N)
