Question

The general formula for alkynes is:

• A. ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}+2}$
• B. ${\text{C}}_{\text{n}}{\text{H}}_{\text{n}}$
• C. ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}-2}$
• D. ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}}$

Answer 1

The correct option is C ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}-2}$

$\bullet$ Alkynes are hydrocarbons having atleast one triple bond between its carbon atoms. The general formula for alkynes is ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}-2}$.

$\bullet$ Alkanes are hydrocarbons having only single bonds between its carbon atoms. The general formula for alkanes is ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}+2}$.

$\bullet$ Alkenes are hydrocarbons having atleast one double bond between its carbon atoms. The general formula for alkenes is ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}}$.
