Which of the following compounds can be a cyclo alkane?(a) C3H5(b) C5H10(c) C14H30(d) C8H8

Interpretation Introduction

Interpretation: The molecular formula of the cycloalkane has to identfied from the following molecular formula (a) C3H5, (b) C5H10, (c) C14H30, (d) C8H8

Concept introduction:

The hydrocarbons which have a general formula CnH2n are known as Cycloalkanes. Cycloalkanes can be substituted or unsubstituted, when carbon atom is substituted are known as substituted Cycloalkanes or branched Cycloalkanes. A Cycloalkane can be formed when carbon number is more than two. In formula, n is the total number of carbon atoms present in molecule. For example if n is equal to 4 than molecular formula will be C4H8.

Explanation

Reason for correct options

The molecular formula for the Cycloalkanes can be identified by using the formula CnH2n. The given compounds which follows this formula will be a Cycloalkane.

(b) C5H10, the number of carbon atoms are 5. The molecular formula of Cycloalkanes having five carbon atoms is calculated as below,

The number of carbon atoms are 5.

Substitute 5 for n in the formula.

C5H2(5)=C5H10

Therefore the compound C5H10 is a Cycloalkane.

Hence the correct option is option (b)

Reason for incorrect options

The molecular formula for the Cycloalkanes can be identified by using the formula CnH2n. The given compounds which follows this formula will be a Cycloalkane.

(a) C3H5, the number of carbon atoms are 3. The molecular formula of Cycloalkanes having three carbon atoms is C3H6. Therefore C3H5 is not a Cycloalkane.

(c) C14H30, the number of carbon atoms are 14
