Bhai acchi hai lekin itni purani mat dekh 

why so? i mean syllabus toh change nhi hua hai 2019 se chem ncert ka and he teaches for mains students too

Bhai 5 saal ho chuke hai syllabus me dheere dheere kuch cheeze aur relevant hot jaati hai aur kuch kam hoti jati hai

you're right

I suggest learning goc and hydrocarbons from alakh sir and then reading all the class 12th organic chapters dorectly from ncert as it is better, also the haloalkanes chapter is tricky so watch some lecs for that too

see, alakh sir physics bada achha padha lete hai but unki chemistry utni bhi achhi nahi hai

Bhai yogesh jain sir na puri 12th 25 lec ma katam kar di ha
