Answer the question in the file. it is to name the alkane

6-ethyl-6,7-dimethyl-3-propylnonane

Explanation:

Step 1: Select the longest carbon chain.

The one with 9 carbons is the longest carbon chain. (Refer to the attached file)

So, this chain is the parent name.

Prefix for 9 carbons : Non-

Suffix used : -ane (Since all the carbons are singly bonded)

Parent name: Nonane

Step 2: Refer to side chains/branches now:

Branch 1: Ethyl on Carbon-6 (6-ethyl)

Branch 2: Methyl on Carbon 6 and 7 (6,7-dimethyl)

"di" because we have 2 methyl

Branch 3: Propyl on Carbon-3 (3-propyl)

While going along with alkyl side chains, we follow the alphabetic order.

So, The name of this compound is:

6-ethyl-6,7-dimethyl-3-propylnonane

Hope this helped!

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

it's all four options.
