Answer 2

Answer:

In order to draw any chemical structure of the compound, one needs to be clear in the nomenclature. Also for representation, any one among the Kekulé , Condensed or Line methods could be used. Here, in the given question 6-methyl hept-3-yne, first we need to figure out the number of Carbon atoms in the structure.

Since the structure has the word heptyne, it is clear that the structure has 7 Carbon atoms. It is also clear that the structure is an alkyne having C≡C in its structure that too in the 3rd Carbon atom

Moreover, from the name of the chemical compound it could be seen that there is a methyl compound in the 6th Carbon atom. The other bonding with carbon atoms will be filled with Hydrogen. Analysing this, the condensed formula of the compound is,                    

                             H₃-C-CH₂-C≡C-CH₂ -CH(CH₃)-C-H₃

 The detailed Kekulé/Lewis structure is as attached in the image below.
