Trick to Remember Some bi-carboxylic acid
🌟1.Oxalic acid- 0 carbon- Oh
🌟2.Maleic acid- 1 carbon- My
🌟3.Succinic acid- 2 carbon- Sun
🌟4.Glutamic acid-3 carbon- Go
🌟5.Adipic acid- 4 carbon- And
🌟6.Palmitic acid- 5 carbon- play
Number of carbons refers number of -CH2 group between two COOH group.
For e.g HOOC-COOH (OXALIC ACID) there is no CH2 group between carboxyl. Maleic acid is HOOC-CH2-COOH there is one CH2 group in betwen. This is how you can remember some bi-carboxylic acid.

Electric Charges and Fields
1. Electric Charge Charge is the property associated with matter due to which it produces and experiences electric and magnetic effect.
2. Conductors and Insulators Those substances which readily allow the passage of electricity through them are called conductors, e.g. metals, the earth and those substances which offer high resistance to the passage of electricity are called insulators, e.g. plastic rod and nylon.
3. Transference of electrons is the cause of frictional electricity.
4. Additivity of Charges- Charge are scalars and they add up like real numbers. It means if a system consists of n charges q1, q2, q3 , … ,qn, then total charge of the system will be q1 +q2 + … +qn.
5. Conservation of Charge The total charge of an isolated system is always conserved, i.e. initial and final charge of the system will be same.
6. Quantisation of Charge -Charge exists in discrete amount rather than continuous value and hence, quantised.
Mathematically, charge on an object, q=±ne
where, n is an integer and e is electronic charge. When any physical quantity exists in discrete packets rather than in continuous amount, the quantity is said to be quantised. Hence, charge is quantised.
7. Units of Charge
(i) SI unit coulomb (C)
(ii) CGS system
(a) electrostatic unit, esu of charge or stat-coulomb (stat-C)
(b) electromagnetic unit, emu of charge or ab-C (ab-coulomb)
1 ab-C = 10 C, 1 C = 3 x 109 stat-C
