Why is ethanoic acid weaker than benzoic acid?

Posted by P S 7 years ago

CBSE > Class 12 > Chemistry

1 answers

Yogita Ingle 7 years ago

This is due to stronger acids have lower pKa value.The ethanoic acid(pKa=476)is a weaker acid than benzoic acid(pKa=419)arcic;
There is electron withdrawing groups which increase the acidity of carboxylic acids by stabilising the conjugate base through delocalisation of the negative charge by inductive and resonance effects.The presence of benzene ring in benzoic acid,delocalisation of electron make it more acidic than ethanoic acid but such stabilization is not present in ethanoic acid.

And at last apply hoffmann brodamide which will give methylamine

Saumya Agrawal 7 years ago

1 convert ethylamine to ethyl alcohol by reacting with NaNO2+HCl 2. Now convert ethyl alcohol to ethanoic acid by oxidation 3. React ethanoic acid with NH3 it will form ethanamide

ANSWER

Chloroacetic acid is more stronger than acetic acid . Why ?

Posted by Mansi Sharma 7 years ago

CBSE > Class 12 > Chemistry

2 answers

Aryan Rai 7 years ago

That's why Chloroacetic acid is stronger than acetic acid.

Aryan Rai 7 years ago

In chloroacetic acid, Cl atom has -I effect . Which attracted O-H bonding electron towards oxygen . So O-H bond dissociates and easily gives H+ ion . In acetic acid -CH3 group has +I effect. Which increases electron density on O-H bond , so acetic acid can't easily donate proton.

Out of amylose and amylopectin which is soluble in water and why?

Posted by Rajni Jindal 7 years ago

CBSE > Class 12 > Chemistry

3 answers

Aryan Rai 7 years ago

Amylose is less soluble in water than the amylopectin. Because of its tightly packed helical structure, amylose is more resistant to digestion than other starch molecules and is therefore an important form of resistant starch.

What are main 3 difference

Yogita Ingle 7 years ago

Ideal solution: An ideal solution may be defined as the solution which obeys Raoult’s law over the entire range of concentration and temperature and during the formation of which no change in enthalpy and no change in volume takes place.
Non ideal solution: A solution which does not obey raoult's law is called non ideal solution.

Rohan Nigam 7 years ago

simply the solution which follow the raoults law is ideal and which not that is non ideal☺

ANSWER

D block elements exhibit more oxidation States then F block elements. Give reason

Posted by Chesta Jain 7 years ago

CBSE > Class 12 > Chemistry

1 answers

Yogita Ingle 7 years ago

Except 1st and last member of transition series all other Transition metal exhibit variety of oxidation state. This is because the difference of energy between (n-1)d & ns electron is very small. Hence electron from both the energy level can be removed to exhibit variable oxidation state . In F block element the energy difference is very large in between two orbital and hence are not available for bond formation or less number of oxidation state.
