Question

How many secondary (2°) carbons are found in 5-ethyl-3,3,4-trimethylheptane??

Answer 1

Answer:

3 secondary carbons are found in 5-ethyl-3,3,4-trimethylheptane.

Explanation:

5-ethyl-3,3,4-trimethylheptane's structure can be seen in the attached picture, in this structure, each vertex represents one carbon atom.

A secondary carbon is a carbon that is bonded to only 2 other carbon atoms, each secondary carbon is highlighted in blue in the attached picture.

Answer 2

There are three secondary carbon atoms in 5-ethyl-3,3,4-trimethylheptane

Organic compounds are usually made up of long chains of carbon. Carbon has the ability to catenate in organic compounds leading to compounds with infinitely long chains.

When a carbon atom is bonded to a single carbon atom, such carbon atom  is primary(1°). A carbon atom that is bonded to two other carbon atoms is a secondary(2°) carbon atom. A carbon atom that is bonded to three other carbon atoms is a tertiary(3°) carbon atom.

There are three secondary  carbon atoms in 5-ethyl-3,3,4-trimethylheptane as we can see from the image attached to this answer.
