Answer 1

1. 2n

Step-by-step explanation:

Answer 2

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.
