is it true that if no of bonds in an atom increases then the atom acquires a positive charge on it and when it loses one bond it acquires a negative charge on it ?
why does it happen so?
Asked by kaziryan.05 | 6th Jul, 2021, 11:31: PM
When number of bond increases it acquires poistive charge it happens in ions like- NH4+ , H3O+
Number of bonds are increased because one extra atom is attached with and one atom from lone pair is released.
For Example in NH3 - One lone pair and 3 bonds are present
In NH4+ ion- One electron from the lone pair is attached one new H and positive charge is due to release of one electon from N.
It is the only posssibility when octet of N is complete with this positve charge.
For negative charge also, To complete the octet of central metal atom one less bond type of structure is formed with negative chargee.

- sir/madam, this doubt will be lenghty. request peace reading. the doubt is w.r.t chapter Amines; to be specific it is w.r.t basicity of amines. in the topic of the comparision of the basic character of alkylamines with ammonia, the order of basicity of amines is tertiary> secondary> primary in gaseous phase, only due to the +I effect. in gasous phase only +I effect is shown? also in the aqueous phase, the disturbancy in the order of basicity is due to the sum of effects of +I effect, solvation effect and steric hindrance? the order of the stability of the following in aqueous phase: +I effect: tertiary> secondary> primary solvation: primary > secondary > tertiary steric hindrance: primary > secondary > tertiary so does it means that +I is effected in both gaseous and aqueous phase but solvation and steric hindrance are effected only in aqueous phase? also sir there is an order of basicity when R= CH3 group and when R= C2H5 group: R= CH3: secondary> primary> tertiary R= C2H5: secondary> tertiary> primary so sir can we generalise the order that: when R=CH3 group, the order of basicity: secondary> primary> tertiary and when R> CH3 group, the order of basicity: secondary> tertiary> primary
