Which of the following statement is/are true 1) PH_5 and BiCl_5 donot

1.	Which of the following statement is/are true 1) PH_5 and BiCl_5 donot exist 2) p - d bond is present in SO_2 3) I_3^(+) has geometry 4) SeF_4 and CH_4 have same shape
Answer» 1,2,3 1,3 1 and 2 1,2,4 Solution :`SeF_4` has distrorted TRIGONAL bypyramidal & `CH_4` has TETRAHEDRAL
