Vedclass · Answer

(B) The melting points of group $13$ elements do not show a regular trend due to the differences in their atomic structures and the effect of the $d$-block contraction (specifically in $Ga$).The melting points are as follows:$B$ $(2349 \ K)$ > $Al$ $(933 \ K)$ > $Tl$ $(577 \ K)$ > $In$ $(429 \ K)$ > $Ga$ $(303 \ K)$.Thus,the correct order is $B > Al > Tl > In > Ga$.

What is the correct order of melting points for the elements of group $13$?
