Question

IF CORRECT ANSWER WITH BRIEF EXPLANATION "WILL MARK AS BRAINLIEST"
A compound with molecular mass 180
is acylated with CH3COCl to get a
ocmpound with molecular mass 390.
The number of amino groups present
per molecule of the former compound
is
1) 2 2) 5
3) 4 4) 6

Answer 1

Answer:

5

Explanation:

For 1 NH  

2

​  

→14+2=16 It turns into NH−COCH  

3

​  

→14+1+12+16+12+3=58 ⇒58−16=42units

So for every NH  

2

​  

, there will be an increase of 42g after acylation.

⇒ The total increase in mass = 390−180 = 210

⇒ No. of amino groups  

42

210

​  

 = 5

⇒ 5 amino groups
