Is SiH3 a strong base?

(SiH3) N is a weaker base than(ch3)3N because in (SiH3) N the lone pair of nitrogen gets delocalise into the empty d-orbital of silicon via back bonding and hence lone pair concentration on nitrogen decreases whereas in (ch3) 3N, carbon atom does not contain any d- orbital and so there is no back bonding and so the …

Which of the following is a weaker base N SiH3 3?

(SiH3)HN is a weaker base than (CH3)3N. Statement-2. Due to pπ-dπ back bonding the availability of electrons on the N atom in (SiH3)+(3)N decreases.

Is N SiH3 3 more basic than?

Lone pair of electrons on N in N(SiH3)3 are used up in p-pie d-pie back bonding while in N(CH3)3 such back bonding is not possible due to the absence of vacant d-orbital in carbon. Therefore, N(CH3)3 is more basic than N(SiH3)3.

Why is CH3 3N a strong Lewis base?

Basicity can be account by the availbility of electron in case of (CH3)3 N there is more electron avaliable than (CF3)3 . In (CH3)3 N the lone pair of N is concentrated on N and so it can act as an electron pair donor (Lewis base).

Is SiH3 3N planar?

So it has a planar structure. It is because of Back bonding by Si atoms, N gains a partial double bond character making it planar. There is p(pi)-d(pi) back bonding between Si and N . And so N(SiH3)3 has trigonal planer structure.

Why is SiH3 3 trigonal planar?

Nitrogen donates a lone pair of electrons to one of the $SiH_3$ which leads to the formation of double bond, the nitrogen atom has a sp3 hybridization, 3 of the hybrid orbitals participate in the bond formation. In trisilylamine three \[s{p^2}\] orbital’s are used for sigma bonding, giving a plane triangular structure.

Is CH3 3N a Lewis base?

(CH3) 3N is a lewis base due to the presence of lone pair on nitrogen atom.

Why is CH3 3N a weak base?

The dissociation of trimethylamine is shown below. From this, it shows that trimethylammonium is a weak base when it is dissolved in aqueous solution because it does not dissociate completely. Therefore, (CH3)3N ( C H 3 ) 3 N in an aqueous solution will be classified as weak base.

Is CH3 3N a strong or weak acid or base?

The compound trimethylamine, (CH3)3N, is a weak base when dissolved in water.
