The decreasing order of stability of the following anions is:

Which of the following represents the hyperconjugation effect?

The basic strength of $1,8-$bis(dimethylamino)naphthalene is $10^{10}$ times more than $1-$dimethylaminonaphthalene. The reason for this high basic strength is:

Explain the terms Inductive and Electromeric effects. Which electron displacement effect explains the following correct orders of acidity of the carboxylic acids?
$(a)$ $Cl_3CCOOH > Cl_2CHCOOH > ClCH_2COOH$
$(b)$ $CH_3CH_2COOH > (CH_3)_2CHCOOH > (CH_3)_3C \cdot COOH$

In which of the following molecules do all the effects,namely inductive,mesomeric,and hyperconjugation,operate?

In $CH_3(3) - CH_2(2) - CH_2(1) - Cl$,give the increasing order of the inductive effect for carbon atoms $1, 2,$ and $3$.
