Multiple choice The Quadruple bonds occurs in which of the followings compound? [Re2Cl8]-- [Pt(Cl)2(PPh3)2] [Co(NH3)4Cl2] [Mn2(CO)10] None of these Reveal answer Fill a bubble to check yourself A Correct answer Explanation This option is correct, because two Re atoms have eight electrons will occupy one sigma. Two pi and one delta bonding to form quadruple bonds between two Re atoms, i.e., Re-Re distance short to exist eclipsed form.
