WebIn a cyclic hydrocarbon compound with alternating single and double bonds, each carbon is attached to 1 hydrogen and 2 other carbons. Therefore, each carbon is sp2 hybridized and has a p orbital. Let's look at our previous example, benzene: Each double bond ( π bond) always contributes 2 π electrons. WebReturn the number of nice pairs of indices. Since that number can be too large, return it modulo 10 9 + 7. Example 1: Input: nums = [42,11,1,97] Output: 2 Explanation: The two pairs are: - (0,3) : 42 + rev (97) = 42 + 79 = 121, 97 + rev (42) = 97 + 24 = 121. - (1,2) : 11 + rev (1) = 11 + 1 = 12, 1 + rev (11) = 1 + 11 = 12.

WebJan 23, 2024 · This rule states that if a cyclic, planar molecule has 4 n + 2 π electrons, it is aromatic. This rule would come to be known as Hückel's … WebJul 29, 2016 · Aromatic, because 4n +2 = 6 π electrons in the ring (with n = 1 ), planar, fully conjugated all around, and cyclic. Only one of the lone pairs is actually in a pure 2p orbital perpendicular to the ring, which means those count as π electrons. The other lone pair is actually in a σ (actually, sp2) orbital, so it doesn't count.
