Question

mates and army all are requested to answer this question​

Answer 1

amide group, a functional group –C(=O)N= consisting of a carbonyl adjacent to a nitrogen atom. cyclic amide or lactam, a cyclic compound with the amide group –C(=O)N– in the ring. metal amide, an ionic compound ("salt") with the azanide anion H2N− (the conjugate base of ammonia) or to a derivative thereof R2N−.

The functional group of an acyl halide (acid halide) is an acyl group (RCO―) bonded to a halogen atom. They are named by changing the suffix -ic acid in the name of the parent carboxylic acid to -yl halide.

I hope it will help you

Answer 2

Explanation:

1. The general formula for such an acyl halide can be written RCOX, where R may be, for example, an alkyl group, CO is the carbonyl group, and X represents the halide, such as chloride.
2. In organic chemistry, an amide, also known as an organic amide or a carboxamide, is a compound with the general formula RC(=O)NR′R″, where R, R', and R″ represent organic groups or hydrogen atoms.
