[00:00:00]Hello organic chemistry with the help of 10 questions per chapter. Okay.

[00:00:09][clears throat] Question number one. Which of the following is an example of permanent electron displacement effect?

[00:00:23]No electron displacement effect resonance hyper conjugation and inductive effect these three are okay inductive effect only presorary effect temporary option permanent effect inductive effect now which of the following act as a as Electile question means what? File means loving.

[00:00:57]Okay. Electron loving right of course that's why they are loving electron. Okay.

[00:01:09]First of all this can never be an electrofile. Okay.

[00:01:27]Okay.

[00:01:28]So, this is a what elect.

[00:01:32]Now question number three. Hyper conjugation involves the deoization of check. Hyper conjugation to deoization of sigma electron inductive effect displacement. Okay. not deoization of electronization of pi electron. Okay.

[00:01:52]Now come to question number four. The correct order of stability of carboation.

[00:02:00]First of all, hyper conjugation and then inductive effect.

[00:02:14]We will go with hyper conjugation. Okay.
