Q1-1-33E-a - Organic Chemistry (Mcmurry)

Question

Draw structures for the following molecules, showing lone pairs:

 (a) Acrylonitrile, C₃H₃N, which contains a carbon-carbon double bond and a carbon-nitrogen triple bond

 (b) Ethyl methyl ether,C₃H₈O, which contains an oxygen atom bonded to two carbons 

(c) Butane, C₄H₁₀, which contains a chain of four carbon atoms 

(d) Cyclohexene,C₆H₁₀ , which contains a ring of six carbon atoms and one carbon-carbon double bond

Step-by-Step Solution

Answer

(a) 

          Structure of acrylonitrile

Bond formation in carbon, hydrogen, and oxygen

Carbon makes four covalent bonds, hydrogen makes one covalent bond, oxygen makes two covalent bonds, and nitrogen makes three covalent bonds.

Structure of acrylonitrile

Acrylonitrile contains one carbon-carbon double bond and a carbon-nitrogen triple bond. So, the structure of acrylonitrile C₃H₃N is represented as:
