apply conservation of angular momentum as well as velocity of seperation = velocity of approch bcoz it is elastic collision and e= 1

please support ure answer numerically

A boy says that he had applied a force on a particle and it moved in SHM. he refuses to say whether k is a constant or not. assume that he has worked with +ve x and no other force acted on it.

then

1) As x increases k increases

2) As x increases k decreases

3) As x increases k remains constant

4) Motion cannnot be SHM

melatonin is related to sleep
due to this reason only oineal gland is called the biological click of the body

most probably
Methoxy(1-Methoxy(1-Methoxy))Methane

as we go down a group the intervening d and f orbitals reduce the shielding effect and hence the hold of nucleus on outer s slectrons is reduced. due to this the s electrons are unable to take part in the reactions freely i.e. they are reluctant to take part in a chemical reaction.
this is called the inert pair effect due to which higher elements of a particular group show OS 2 less than the group OS
this is more pronounced in p block elements as they appear just after the d block (or f block elements)

neuron- melanin is the odd pair
it should be neuron- myelin

alk. KMnO4(Baeyer's reagent) or a strong acid like H2SO4

it is a distorted square pyramid due to presence of one one pair of electrons

trueman for theory and GRB books for objective

microglial cells are the actual specialised phagocytes
astrocytes are a type of macroglial cells which are invilved in supporting the nerve fibres and maintaining the blood-brain barrier.

Please tell the reason

Please tell the reason

options are allright

Down the group nucleophilicity increases and basicity decreases

superoctet means outer shell configuration of P contains more than 8 electrons.
structure of PCl5 is also explained under Sudgen singlet theory

Which is more stable and why?

What is the order of stability of following and why???

1)Cyclopropyl carbocation

2)Cyclobutyl carbocation

3)Cyclopentyl carbocatio

its neither vector nor scalar
its a tensor bcoz it has different values in different axes
actually tensor is a generalized term and is characterised by its rank
like scalar is tensor of rank 0 and vector is of rank 1

alc KOH bcoz it guides elimination reaction

In aq KOH it becomes ionic and breaks into K⁺n OH^-

OH^-being a nucleophile guides S_N reaction
