Since carboxylic acids can form hydrogen bonds to create dimers, they have higher boiling points than alcohols and other carbony
Yanka [14]

Answer:

True

Explanation:

The arrangement of three groups COOH, CO, OH in the order of reducing boiling point is as follow -

 COOH > OH > CO

COOH gets strongly polarised due to the presence of electron withdrawing carboxy group and hence have strong H+ bonds as compared to that of alcohol.

Hence the given statement is true.

For the reaction A+2B→C under a given set of conditions, the initial rate is 0.100 M/s.What is Δ[B]/Δt under the same conditions
Oliga [24]

Answer: The rate of disappearance ( -Δ[B]/Δt) under the same conditions is 0.200 M/s.

Explanation:

A+2B\rightarrow C

Initial Rate of the reaction = 0.100 M/s

Rate of disappearance of B:

-\frac{1}{2}\frac{\Delta [B]}{\Delta t}=0.100 M/s

-\frac{\Delta [B]}{\Delta t}=2\times 0.100 M/s=0.200 M/s

The rate of disappearance ( -Δ[B]/Δt) under the same conditions is 0.200 M/s.
