Question

How many sigma bonds are in a molecule of diethyl ether, $(C_2{H}_5{)}_{2}O$?

• A. 14
• B. 12
• C. 8
• D. 16

Answer 1

The correct option is A 14

Structure of $C_2{H}_{5}O$:

$H-\stackrel{H}{\stackrel{|}{\underset{H}{\underset{|}{C}}}}-\stackrel{H}{\stackrel{|}{\underset{H}{\underset{|}{C}}}}-O-\stackrel{H}{\stackrel{|}{\underset{H}{\underset{|}{C}}}}-\stackrel{H}{\stackrel{|}{\underset{H}{\underset{|}{C}}}}-H$

Sigma bonds $=14$
