Question

What kind of alkyl halide is found in a Newman projection?

A) Primary alkyl halide
B) Secondary alkyl halide
C) Tertiary alkyl halide
D) Quaternary alkyl halide

Answer 1

In a Newman projection, an alkyl halide could be primary, secondary, or tertiary, depending on the carbon atom's bonding. Quaternary carbons do not have halogen groups and are not classified as alkyl halides.

Step-by-step explanation:

The kind of alkyl halide that can be represented in a Newman projection is not limited to one particular type; it could be a primary, secondary, or tertiary alkyl halide, depending on the molecular structure being represented. In a Newman projection, the classification of the alkyl halide is determined by the number of carbon atoms (denoted as R groups) attached to the carbon atom that bears the halogen. Specifically:

• If bonded with a primary carbon atom (attached to only one other carbon atom), it is a primary alkyl halide.
• If bonded with a secondary carbon atom (attached to two other carbon atoms), it is a secondary alkyl halide.
• If bonded with a tertiary carbon atom (attached to three other carbon atoms), it is a tertiary alkyl halide.

A quaternary carbon atom, which is attached to four other carbon atoms, does not have any halogen groups and thus would not be classified as an alkyl halide.
