Question

$Statement$: When 2-butyne reacts with triethylamine followed by $B{r}_2$ then meso-2,3-dibromobutane is produced.

If the statement is true enter 1, else enter 0.

Answer 1

2-butyne is partially reduced with sodium in liquid ammonia to obtain 2-butene. A molecule of bromine is then added across a carbon-carbon double bond to obtain meso-2,3-dibromobutane.

Hence, the given statement is $false$.
