1. In a cyclic hydrocarbon with only carbon-carbon single bonds and n number of carbon atoms, how many hydrogen atoms are there in terms of n?A cyclic hydrocarbon containing only carbon-carbon single bonds is called a cycloalkane it has a general formula of CnH2n. Therefore, the correct answer among the choices is the last option.

3. Which of the following molecules does NOT display resonance? 

The answer would be cyclohexane.

A

Explanation:

It's a metal.

Metals in general go positive when the combine with a non metal. Li is going from 0 to 1 and that's A
