Question

Cyclohexanol is dehydrated to cyclohexene on heating with conc. $H_{2}S{O}_{4.}$ If the yields of this reaction is $75$%, how much cyclohexene will be obtained from $100$ g of cyclohexanol? $C_6{H}_{12}O\stackrel{con.H_{2}S{O}_4}{\to }{C}_6{H}_{10}$

• A. 61.5 g
• B. 65.7 g
• C. 69.3 g
• D. 70.9 g

Answer 1

The correct option is A 61.5 g

The amount of cyclohexene obtained from $100$ g of cyclohexane is $100\times \frac{82.1}{100.2}\times \frac{75}{100}=61.5g$.
