For the product of the reaction below, which proton is removed irreversibly by NaNH2 base, thus preventing any isomerization of
Serggg [28]

Answer:

The Highly acidic proton joined to one of the carbon in the ALKYNE bond.

(Kindly Check the attachment for the drawing because the solution will need us to draw).

Explanation:

So, let us start by defining some major key terms in this particular Question given above;

(1). ISOMERIZATION: isomerization can simply be defined as the kind is of chemical rearrangement whichay lead to the breaking and the formation of new bonds.

(2). NaNH2 BASE: Sodium amide is a Chemical compound which has a Molar mass of 39.01 g/mol and Heat capacity (C) of 66.15 J/mol K. It is also known as sodamide. It is a good nucleophile.

(3). ALKYNE BOND: it is a C-C joined together by three bonds.

The chemical reaction given in the Question is given in the attachment too.

Therefore, The Highly acidic proton joined to one of the carbon in the ALKYNE bond  is removed irreversibly by NaNH2 base.

List the following bonds in order of increasing polarity (ionic character). Give the electronegativity values for each atom to j
barxatty [35]

Answer:

A = B < D < C

C - S

Cl - Cl

F ← H

Si → O

Explanation:

The polarity of a bond increases with the increase in the difference in electronegativity. The dipole moment is represented with an arrow pointing the more electronegative atom.

A: carbon-sulfur

C - S

ΔEN = |EN(C) - EN(S)| = |2.5 - 2.5| = 0

B: chlorine - chlorine

Cl - Cl

ΔEN = |EN(Cl) - EN(Cl)| = |3.0 - 3.0| = 0

C: fluorine – hydrogen

F ← H

ΔEN = |EN(F) - EN(H)| = |4.0 - 2.1| = 1.9

D: silicon - oxygen

Si → O

ΔEN = |EN(Si) - EN(O)| = |1.8 - 3.5| = 1.7

The order of increasing polarity is A = B < D < C.
