Answer #1

The degree of unsaturation in the given compound from the given formula is:

DU = (Cn+1) - Hn /2 -Xn/2 + Nn/2

where,

Cn = number of carbon atoms

Hn = number of hydrogen atoms

Xn= number of halogen atoms

Nn= number of nitrogen atoms

The given molecular formula is :

C11H22O.

DU = (11+1) - 22/2

= 12-11

= 1

Hence, degree of unsaturation =1

This indicates that the given molecule may contain either one double bond or a ring.

From the given proton NMR:

The structure of the molecule is:
