What are carbylamines ?

Explanation

### Step-by-Step Solution:

**Step 1: Definition of Carbylamines**
Carbylamines, also known as isocyanides, are organic compounds formed when an alkyl or aryl group is attached to the isocyanide functional group (-N≡C). The general formula for a carbylamine can be represented as R-N≡C, where R is either an alkyl (a carbon chain) or an aryl (an aromatic ring) group.

**Step 2: Characteristics of Carbylamines**
Carbylamines are known for their distinctive and unpleasant odor, which is why they are often referred to as foul-smelling substances. This characteristic is significant in organic chemistry, particularly in the identification of certain compounds.
