Question

Draw a Newman projection along the C2-C3 bond of the following conformation of 2-butanol.

Short answer

The different conformations of a particular molecule can be understood using the Newman projection.The three lines seen in Y shape indicate the three bonds of the first carbon in the Newman projection.

Step-by-step solution

Newman projection

The different conformations of a particular molecule can be understood using the Newman projection.The three lines seen in Y shape indicate the three bonds of the first carbon in the Newman projection.

Drawing the Newman projection along the C2-C3 bond of the following conformation of 2-butanol

2-Butanol or sec-butanol is an organic compound with the formula ${\mathrm{CH}}_3\mathrm{CH}\left(\mathrm{OH}\right){\mathrm{CH}}_2{\mathrm{CH}}_3$

The staggered conformation of 2-butanol is the most stable as the two methyl groups are situated away from each other and do not experience repulsion. The eclipsed conformation is the least stable conformer as the two bulky groups lie close to each other.

The Newman projection of the structure can be given as:
