Question

Name this compound.

• A. 4-isocyano-prop-1-ene
• B. Prop-3-en-1-carbylamine
• C. Prop-3-en-1-isonitrile
• D. Prop-1-en-4-isonitrile

Answer 1

Answer: (B), (C)

Prop-3-en-1-isonitrile

In the order of preference of functional groups, -CN precedes alkenes. Since alkene doesn't have any suffix, both will be suffixed

Longest chain would be 3 carbons.

Word root = prop

-CN has 2 different suffixes both of which are accepted. They are carbylamine and isonitrile

So, Prop-3-en-1-carbylamine or Prop-3-en-1-isonitrile
