Introduction

Organic chemistry is a chemistry sub discipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.

Pre-Requisites:

Key Words / FlashCards
Key Words Definitions (pref. in our own words)
Hyper conjugation Hyper conjugation is the interaction of the electrons in a sigma bond (usually C–H or C–C) with an adjacent empty (or partially filled) non-bonding p-orbital, antibonding ? orbital or filled ? orbital, to give an extended molecular orbital that increases the stability of the system.

Gadgets How it can be used
Alcohols Alcohols (R-OH) take the suffix "-ol" with an infix numerical bonding position: CH3CH2CH2OH is propan-1-ol. The suffixes -diol, -triol, -tetraol, etc., are used for multiple -OH groups: Ethylene glycol CH2OHCH2OH is ethane-1, 2-diol.
Real life uses :

Study the nature of chemicals.

Practical examples around us
Examples Explainations
ketones In general ketones (R-CO-R) take the suffix "-one" with an infix position number: CH3CH2CH2COCH3 is pentan-2-one. If a higher precedence suffix is in use, the prefix "oxo-" is used: CH3CH2CH2COCH2CHO is 3-oxohexanal.
What you learn in Theory:

Hyper conjugation is the interaction of the electrons in a sigma bond (usually C–H or C–C) with an adjacent empty (or partially filled) non-bonding p-orbital, antibonding ? orbital or filled ? orbital, to give an extended molecular orbital that increases the stability of the system.

What you learn in Practice:

Only electrons in bonds that are ? to the positively charged carbon can stabilize a carbocation by hyper conjugation.
