Assertion : Alkyl isocyanides in acidified water give alkyl formamides. Reason : In isocyanides, carbon first acts as a nucleophile and then as an electrophile.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion
- BIf both assertion and reason are true but reason is not the correct explanation of assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion
Step-by-step solution
In an isocyanide, first an electrophile and then a nucleophile add at the carbon to form a species which usually undergoes further transformations. array r R + N C +E⁺ R + N CE Nu RN = C ( Nu ) E R_ + ^ N C + H ₂ O R ~N = CHOH R NHCHO array alkyl formamide
