2024年5月24日 · The net charge of CH2 is neutral because carbon has a charge of +4 and hydrogen has a charge of +1, so the two hydrogen atoms balance out the positive charge of the carbon atom.

Consider what the electrons are doing in the pi bond, they are attacking the delta+ bromide (in that mechanism, although it's a tad weird: I would think they go to the methylene group at the end, but I digress). Now the carbon atom only has three bonds: one to carbon and two to hydrogen, hence the positive charge, that is a very great substrate for the nucleophilic bromide hanging out in …

2015年10月13日 · See explanation. If we consider the delocalization through the entire backbone of the molecule, the canonical forms (resonance structures) could be represented as follow: The structure with no charges would be the major contributor and therefore the more stable form. The carbocation would be very unstable especially on a primary carbon atom ""^+CH_2-.

2024年6月6日 · In organic compounds, carbon forms four bonds for all practical purposes. There is a compound called methylene, CH2, but it is extremely reactive. The compound CCl2 can also be formed from the ...

2025年2月21日 · CH2 is nonpolar because it has a symmetrical structure with carbon at the center, causing the electronegativities of the hydrogen atoms to cancel out.

2018年4月28日 · The Lewis structure of CH3:- is The carbanion has three bonding pairs and one lone pair. Thus, VSEPR theory predicts a tetrahedral electron geometry and a trigonal planar electron geometry. A tetrahedral electron geometry corresponds to sp3 hybridization.

2018年2月12日 · Using the Pka' Values for glutamic acid (pk1= 2.19, pk2= 9.67, pkR= 4.25) indicate the ionic form which predominates at: a) pH 1.0 b)pH 7.0 c) pH13 d) What is the net charge of the predominant form at each of these pH's?

2024年6月6日 · The compound is known as isopentane or 2-methylbutane. It is a pentane molecule containing a single CH bond and 3 CC bonds to one of the 5 carbon atoms, with three CH3 groups and a CH2.

2017年12月18日 · They increase the charge density in the carboxylate ion and make the acid weaker. However, CH3 is a stronger electron donating group than H, so it has a greater weakening effect.

2024年6月5日 · The molecular formula of the compound CH2 with a molar mass of 168 g/mol is C8H16 since the molar mass of carbon is approximately 12 g/mol and the molar mass of hydrogen is approximately 1 g/mol.
