Question
Ring strain the cause of high molecular reactivity that occurs when the angles in a ring of atoms are not close to "normal" bond angles (90 when the bonds are formed by atoms using pure p-orbitals, 109.5 using sp3 hybrid orbitals, 120 using sp2 orbitals, etc.). The angles in white phosphorus, P4, measure ________, and P4 ________ (is, is not) expected to exhibit ring strain and be very reactive.Answer
