Question

Which of the following represent the Sawhorse projection of butane molecule ?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Option (a) is the Newman representation of butane molecule.
Option (b) is the Fischer representation of butane molecule.
Option (c) is the Sawhorse representation of butane molecule.
Option (c) is the Wedge dash representation of butane molecule.
Saw horse projection is a representation of molecular structure, from an oblique angle. It is similar to a Newman projection, but it shows the carbon-carbon bond that is hidden in a Newman projection. We can Sawhorse projection for both eclipse and staggered conformation. Option (c) represent the Sawhorse projection for eclipsed conformation of butane.
Hence, option (c) is correct.
