Derivatives

mesomeric

adjective

Chemistry

Mesomeric effects are much better transmitted through bonds than the inductive effect; in the C 3 position, the effect of the the carbonyl mesomeric influence is still noticeable.
Example sentencesExamples
- In this case the I effect of the halomethyl group is not exceeded by a positive mesomeric effect as for instance in case of methyl vinyl ether.
- The rearrangement of cross-conjugated mesomeric pyrimidines has been extensively studied.
- An indication of oxidation numbers or formal charge in Lewis structures and the resulting mesomeric structures is important in some branches of chemistry.
- Some problem arose at the alkylation of aromatic thiols substituted by substituent with positive mesomeric effect in the benzene ring and various copper heterogeneous catalysts at the same time.
