Hello candidate,

1. When 2-Bromo Propane undergoes dehydrohalogenation, action involves the removal of halogen and hydrogen group with the addition of a double bond which gives rise to the product as Pentene.

2. When Methyl Bromide reacts with potassium cyanide, then a simple substitution reaction happens which gives the product

Hello aspirant,

Hope you are doing well

Elements of the lanthanide class have the most permanent oxidation state of +3, which is why lanthanides generally exhibit a +3 oxidation state. There are some lanthanide elements that exhibit +2 and +4 oxidation states, also known as incompatible oxidation states.

Hope this

Hello,

structure of Propionic alcohol

CHOH

C - H-OH

Propanoic alcohol

It is a liquid with pungent and unpleasant  smell.

It is prepared from propanoic acid

The difference between 1- propanol and 2- propanol is position of OH group.1- propanol is chain structure while 2- propanol is branched structure.These

2nd excited state implies that n=3.

Now the inner most radius i.e., for n=1, r'= 5.3*10^-11 m

Now we know radius of nth orbit is given by r(n) = r' * n^2

There the radius of the second excited state i.e., r(n =3) = r' * 3^2 = 5.3*10^-11*9 =

Dear Student,

amino acids are essentially an organic compound which contains the compounds of amine and carboxyl functional groups along with a side chain specific to each amino acid.

Amino acids are amphoteric since they tend to have acid and basic tendencies. The carboxyl group of the amino acid is

Hello aspirant,
