Predict the product: NHCH3 + NaNO2 + HCl → Product

1. (i) CH3CH(OH)CH3 (iv) with Lucas reagent cloudiness appears after 5 minutes
2. (ii) CH3N—NO2
3. (iii) CH3N=N—O
4. (iv) CH3CH(OH)CH3

Correct answer: (iii) CH3N=N—O

Solution

The reaction involves methylamine (NHCH3) reacting with NaNO2 and HCl, leading to the formation of a diazonium ion intermediate, which rearranges to form CH3N=N—O (option C).
