WebOct 20, 2024 · Facts I know: 1) More the electron density in benzene ring, the faster the reaction. 2) Lone pair on -OCH3 group undergoes resonance and makes ortho-para positions electron rich, and so does -CH3 by hyperconjugation. 3) -OCH3 group shows -I (electron withdrawing) and -CH3 shows +I (electron releasing). WebAug 4, 2024 · Let's say we have a methyl group bonded to a positively-charged carbon atom with a vacant p orbital. Ideally, it would be best if we could have an atom with a fully-filled p orbital, which is parallel to the p orbital of the this positively-charged carbon atom, to come and interact with this carbon atom.
Which one is more electron donating, ethyl, methyl or …
Webq We can easily understand this because alkyl groups are electron donating(EDG), so they stabilize the positively charge ammonium ions, i.e., the methyl ammonium ion is more stable than the parent ammonium ion because the alkyl group stabilizes the positive charge on the attached nitrogen atom. WebIn the following diagram we see that electron donating substituents (blue dipoles) activate the benzene ring toward electrophilic attack, and electron withdrawing substituents (red dipoles) deactivate the ring (make it less reactive to electrophilic attack). danbury shakes handwriting
Which one is more electron donating, ethyl, methyl or phenyl group?
WebDec 30, 2015 · This means that there are electrons in its valence shell that have not participated in covalent bonding. The alkyl group's tendency to donate electrons derives from this fact. Electronegativity is defined as the tendency of an atom of an element to draw electrons towards itself in a covalent bond. WebAlkyl groups – methyl, ethyl, and the like – are weak electron donating groups, and thus stabilize nearby carbocations. What this means is that, in general, more substituted carbocations are more stable : a tert-butyl carbocation, for example, is more stable than an isopropyl carbocation. WebAlkyl groups – methyl, ethyl, and the like – are weak electron donating groups, and thus stabilize nearby carbocations. What this means is that, in general, more substituted … danbury sheds maldon
