How does the atomic radii trend explain the electronegativity trend?

1 answer:

3 0

Answer is: electronegativity decreases with increase of atomic radius, because of increased distance between the valence electrons and nucleus, so atoms tends to lose electrons easier.

Electronegativity<span> is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.</span>

The atomic radius of a chemical element is a measure of the size of its atom.The atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.The atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

Answer:

The PH2 becomes attached to the alkyl halide with inversion of configuration

Explanation:

SN2 reaction involves the simultaneous attachment of the nucleophile as the leaving group departs. This leads to an inversion of configuration because the sterochemistry around the carbon bearing the leaving group is reversed. The reaction proceed via a crowded five coordinate transition state. Details are shown in the image attached.
