Question

Which structure represents nonane?

A.
one carbon atom forming single bonds with four hydrogen atoms
B.
two carbon atoms forming single bonds with six hydrogen atoms
C.
5 carbon atoms forming single bonds with 12 hydrogen atoms
D.
9 carbon atoms forming single bonds with 20 hydrogen atoms

Answer 1

Answer:

According to nomenclature, 'Non' is the root word depicting 9 carbon atoms in the structure and 'ane' at the end depicts the compound to be alkane.

We know that, General Formula of Alkane = Cₙ H₂ₙ₊₂

Here 'n' refers to number of Carbon atoms

According to Question, Nonane has 9 carbon atoms. Hence n = 9

Substituting in the formula we get,

C₉ H₂₍₉₎₊₂ = C₉ H₂₀

Hence Formula of Alkane is C₉H₂₀

Hence it is covered by 20 hydrogen atoms.

Hence, Option d is correct.

Thanks !!

Answer 2

Answer :-

Nonane means 9 Carbon atoms which are formed by single bond and they belongs to Alkane Group.

=> By Alkane Compound Formula,

Cn + 2(2n+2)

=> C9 + 2(2×9 +2)
=> C9 + 2(20).

It means it is forming bond with 20 Hydrogen atoms.

Hence, Option D is correct Answer.

=> 9 carbon atoms forming single bonds with 20 hydrogen atoms.
