Question

Alkanes $\left(C_n{H}_{2n+2}\right)$ have :

• A. straight chain
• B. branched chain
• C. cyclic chain
• D. both A and B

Answer 1

Answer: (D)

both A and B

Classification is of two types-
1. Straight chain-In this all the carbon atoms are attached by covalent bonds in a continuous chain.
2. Branched chain- In this the carbon atoms are not in continuous chain and they are linked to other carbon atoms to make branches.
