"Sir is very good teacher .He explains the concept in very good manner. Sir also gives freedom to ask every single doubt we have. He explains the concept in Friendly manner which is good for us to connect with him. Sir gives us live examples frequently. He not only appreciates the topper but also encourages the slow learners. Therefore he is one of the wonderful best teachers I have met "

"Sir's teaching can't be describe in words! I was a student who used hate chemistry and score less in objective tests but with his entry in my life, the chemistry became intresting to me because of his way of explaining the concepts (especially organic chemistry) and in physical chemistry he used to explain the concepts in depthly then explain few questions of different models like how to solve them. Overall I started scoring well in tests. "

Hello Aspirants,
Atomic number (Z) is the identity of the atom.
Atoms of different elements have their own Atomic number.
Atomic number gives the information about number of protons present in the nucleus.
Protons are the positively charged sub-atomic particles. They are present in the nucleus.
So, the number of protons in the nucleus = Atomic number(Z).
Atomic Number(Z) also gives the information about number electrons present in the atom, but the atom must be neutral.
Thank you.

Hello Aspirants,
But-2-ene is the systematic IUPAC name.
"But" is the Root word, it means the compound has 4 carbon atoms.
2-ene is the 1º suffix. It means that there is double bond in the compound.
The position of the double is on 2nd carbon.
The double bonded carbon atoms have SP² hybridisation. It gives planner geometry. The C=C bond hinders the free rotation.
Due to this the two CH3 groups may present same side with respect to the double bond. It is called CIS-ISOMER.
The two CH3 groups may also present opposite side to the double bond. It is called TRANS-ISOMER.
This phenomenon is called Geometrical isomerism, which comes under Stereo-isomerism/space isomerism.
Thank you.

Hybridization expalains the formation and structure of heteroatomic molecules. According to hybridization theory
in
B is the central atom which underoes hybridization. B has 3bond pairs with no lone pairs.
has trigonal planar geometry. (just like fan)
in
C is the cental atom. C undergoes hybdridization. C has 4bond pairs with no lonepairs.
has tetrahedral geometry.
in
C is the cetral atom. C undergoes hybdidization. C has 2bond pairs withno lone pairs.
has linear geometry.
in
N is the central atom. N undergoes hybdidization. N has 3bondpairs with 1lone pair..
has pyramidal geometry.
