Question

The boiling points of ethyl acetate and CH3OH,
respectively, are 77°C and 65°C. Which of the
following reactions can be shifted to the right by the
distillation of the reaction mixture at about 66°C
I) MeCOOEt + MeOH →
II) MeCOoMe+ EtOH →
III) MeCOOMe+ PhOH →
IV) MeCOOPh+MeOH →​

Answer 1

Answer:

A plane angle is one that can be measured completely within a plane. This may be because the angle occurs in a 2-D space, or it is an angle that is contained completely within a plane that is in a 3-D (or higher-D) space.

So the angles in a triangle are plane angles, because they are in a plane. Similarly, the angles in a spherical triangle are plane angles, because even though they measure things in a 3-D space, they can always be shown to be wholly within a plane.

Another way to consider a plane angle is to think of angles within a circle. You can divide the circle up into 2π radians, for example, or 360°, or 400 gon, or whatever units you choose. However, the radian as a unit is defined by the subtended arc length that is equal to the radius of the circle

Answer 2

Answer:

(I),(II)

(II),(III)

(I),(III)

(II),(IV)

Answer :

D

Solution :

In (II), the product are ethyl acetate (boiling point 77∘C) and MeOH(boiling point 65∘C). Thus at 66∘C, MeOH is removed due to distillation and equilibrium is shifted to R.H.S.

In (IV), phenyl acetate is more reactove than methyl acetate.
