Webnaphthol is [4n+2] π-aromatic in the ground state (red) but becomes [4n+2] π-antiaromatic in the S1 state (green). Deprotonation relieves excited-state antiaromaticity, stabilizing the excited conjugate base (light green). In the S0 state, the conjugate base (light red) is only moderately less aromatic than the acid. Table 1. WebOne of the following hydrocarbons is mu much more acidic than others.

WebUnlike aromatic compounds, which follow Hückel's rule ( [4 n +2] π electrons) [1] and are highly stable, antiaromatic compounds are highly unstable and highly reactive. To avoid the instability of antiaromaticity, molecules may change shape, becoming non-planar and therefore breaking some of the π interactions. WebBaird first proposed a set of rules suggesting that the electron-counting rules of aromaticity and antiaromaticity reverse in the lowest triplet states of π-conjugated cycles. 1 Based … towara arbeitsrechtWebof aromaticity. For this reason, we proposed4 the term “antiaromatic” to describe such systems. A cyclic conjugated system is considered to be antiaromatic if its € electron energy is higher than that of a suitable reference compound which is not cyclically delocalized.
