Chapter 5: Q5-52P (page 222)

Squalene, a hydrocarbon with the molecular formula C30H50, is obtained from shark liver. (Squalus is Latin for 鈥渟hark.鈥�) If squalene is an acyclic compound, how many 蟺 bonds does it have?

Short Answer

Expert verified

Squalene, a hydrocarbon with the molecular formula C30H50, is obtained from shark liver. (Squalus is Latin for 鈥渟hark.鈥�) If squalene is an acyclic compound, then it has 6 p bonds.

Step by step solution

01

What is the degree of unsaturation

The total number of p bonds and rings in a hydrocarbon is called degree of unsaturation.

What is p bond-

When formation of double bond or triple bond occurs then there will be the presence of p bond. In double bond there is one p bond and in triple bond there is two p bonds. p bond is formed with the help of two electrons so when p bond is formed two hydrogens will become less than the simple hydrocarbon chain.

When ring formed then also two hydrogen will become less from the simple hydrocarbon chain.

02

How to find

a)For a 30-carbon hydrocarbon with no p bonds and no rings, CnH2n + 2 = C30H62. A

30-carbon compound with molecular formula C30H50 has twelve fewer hydrogens, so the degree of unsaturation is 12/2 = 6.
