Problem: Draw the condensed structure of 3-methyl-1-butyne.

FREE Expert Solution

The condensed method is a common way to describe the connectivity of a molecule using only text.

The use of parentheses is important:

  • Parentheses with no subscripts: Branch on the chain.
  • Parenthesis with subscripts: Multiple branches on a chain.
  • CHwithin parentheses + subscripts: Repeating CHunits within a chain.


First, draw the bondline structure:

3-methyl-1-butyne

Root: but → 4 carbon alkane

Modifier: yne → alkyne (triple bond)

                            locant: 1 → Carbon 1

Substituents : methyl → 1 C alkane 

                            locant: 3 → Carbon 3
