Cyclohexanol is dehydrated to cyclohexen...

Cyclohexanol is dehydrated to cyclohexene on heating with conc. `H_(2) SO_(4)`. If the yield of this reaction is `75%` how cyclohexene will be obtained from 100 g of cyclohexanol ?

A

`61.5` g

B

`75.0` g

C

`20.0` g

D

`41.0` g

Text Solution

Verified by Experts

The correct Answer is:
A

100 g cyclohexanol produces = 82 g of cyclohexene
1 g cyclohexanol produces `=82/ 100` g of cyclohexene
If reaction occurs `75%`, then 100 g og cyclohexanol
produces
`=82/100 xx 100 xx 75/100 = 61. 5` g
The weight of cyclohexene formed
`=(82xx100) / 100 xx 75/100 = 61. 5` g
