multiple choise question 2..?

Question

a what is the reaction of acetaldehyde with concentrated sulphuric acid?

1 decomposition
2 polymerisation
3 no reaction
4 charred to black residue


b calcium acetate on heating under distillation gives

1 acetaldehyde and calcium oxide
2 calcium carbonate and acetic acid
3 acetone and calcium carbonate
4 calcium oxide and co2


please third one which I have asked so many times but no one ans it

equivalent cunductance of an electrolyte containing NaFat infinite dillution is 90.1.if NaFis replased by KFwhat is the value of equivalent cunductance?
1 90.1
2 111.2
3 0
4 222.4
values are in ohms cms
please specify if you are not sure

Answer 1

a what is the reaction of acetaldehyde with concentrated sulphuric acid?


Answer 4) 4 charred to black residue

b calcium acetate on heating under distillation gives

1 acetaldehyde and calcium oxide

c) equivalent cunductance of an electrolyte containing NaFat infinite dillution is 90.1.if NaFis replased by KFwhat is the value of equivalent cunductance?
1 90.1, because potassium and sodium has the same charge.

Answer 2

a. 1,sulphuric acid will decompose it
b. 2, calcium carbonate and acetic acid will formed
c. 1,90.1ohms cms bcoz eqvilent conductance will remain same

Answer 3

Better to consult ur chemistry teacher
