The 13th group element having  highest IP1 is Boron .Which element  of this group is having IP1 next to Boron

Easy
Solution

Atomic radius….B<Ga<Al<In<Tl;

IP1…..B>Tl>Ga>Al>In;

MP…B>Al>Tl>In>Ga;

Boron has gaint polymeric structure,Gallium exists as Ga2 molecule(M.P = 302 K)

BP….B>Al>Ga>In>Tl:

Difference in B.P and M.P in Gallium is about 2300 K. It has wide liquid range.It is athermometric liquid.

Density…B<Al<Ga<In<Tl;

EN…B>Tl>In>Ga>Al;

EM3+Mo is most -ve for Al and +ve for Tl;
