Correct order of bond angles for the following is

BCl3​ is sp2 hybridized CH4​ is sp3 hybridized PCl3​ is sp3 hybridized. As the character of p is more the bond angle of central atom is less.However CH4​ and PCl3​ are having same p character but the lone pair on PCl3​ reduces the regular bond angle. So the correct order is BCl3​>CH4​>PCl3​
