Several factors (steric, electronic, orbital interactions etc. ) can affect the inversion barrie of an amine. In the givne pair which data is corretly placed?

Several factors (steric, electronic, orbital interactions etc.) can affect the inversion barrier of an amine. In the given pair which data is correctly placed ?

The molecule , which are electron deficient having tendency to form back bonding, in which transfer of lone pair of electron from filled orbital of an atom to the vacant orbital of the adjacent atom. While some electron deficient species which are not capable to form back bonding, then driving forces occurs for dimerisation/polymerisation to achieve octet temporily or permanently by the monomeric species. Which of the following readily gets combined with lewis base (NH_(3),CH_(3)NH_(2),C_(5)H_(5)N "etc")

Consider the following statements and arrange in the order of true/false as given in the codes. S_1 :In modern periodic table each block contains a number of columns equal to the number of electrons that can occupy that sub-shell S_2 :The greatest increase in ionization enthalpy is experienced on removal of electron from core noble gas configuration S_3 :The size of the isoelectronic species is effected by eletron-electron interaction in the outer orbitals S_4 :Any thing that influences the valence electrons will affect the chemistry of the element and the valence shell is not affected by nuclear mass.

Which of the following has vacant orbitals, that can accept a lone pair of electron?

Amines are basic compounds They act as Lewis base due to the presence of lone pair electrons at nitrogen Amines also behave as base as well as Bronsted inductive effect, steric hindrance and resosnance. CH_(3)-NH_(2)+HOH hArr CH_(3)-NH_(3)^(+)+OH^(-) CH_(3)-NH_(2)+H^(+)Cl^(-)hArr CH_(3)-NH_(3)^(+)+Cl^(-) Alkyl groups and electron groups hence these groups increases the electron density at nitrogen as well as the basic amines character of amines. Basic character of teritary amines is reduced due to the steric hindrance of three alkyl groups. Experimentally it is observed that stronger bases have smaller values of pK_(b) greater value of K_(b) . Which among the following is the most basic in aqueous medium?
