D) 10
Show Answer
Answer:
Correct Answer: C
Solution:
$ C_4H_{10}O $ have 7 isomers out of which 4 are alcohols and 3 are ethers.
1.$ \underset{n-butyl,alcohol}{\mathop{CH_3-CH_2-CH_2-CH_2-OH}}, $ ,
2.$ \underset{Sec-butyl,alcohol}{\mathop{CH_3-CH_2-\underset{OH}{\mathop{\underset{|,}{\mathop{CH}},}},-CH_3}}, $
3.$ \underset{Isobutyl,alcohol}{\mathop{CH_3-\underset{CH_3}{\mathop{\underset{|,}{\mathop{CH}},}},-CH_2-OH}}, $
4.$ \underset{Ter-buty-alcohol}{\mathop{CH_3-\overset{CH_3}{\mathop{\underset{\underset{OH}{\mathop{|}},}{\overset{|}{\mathop{C-,}}},}},CH_3}}, $
5.$ \underset{Diethyl,ether}{\mathop{CH_3-CH_2-O-CH_2-CH_3}}, $
6.$ \underset{Methyl,propyl,ether}{\mathop{CH_3-O-CH_2-CH_2-CH_3}}, $
7.$ \underset{Methyl,isopropyl,ether}{\mathop{CH_3-O-CH<_CH_3^{CH_3}}}, $
