Question

How many rings does an alkane have if its formula is c10h16?

Answer 1

If it is saturated compound then we can calculate the double bond equivalent which will be equal to the number of rings in the compound

the double bond equivalent can be calculated using following formula

$DBE = (C + 1 -\frac{H}{2} - \frac{X}{2} +\frac{N}{2} )$

Where

H = number of Hydrogen atoms

C = number of carbon atoms

X= number of halogen atoms

N = number of nitrogen atoms

DBE = (10 + 1  - 16 / 2 ) = 3

Hence there are three rings in the compound
