@Science-Club when the size of particle lies b/w 1 to 1000nm then it acts like colloid and if less than 1nm then acts as true soln and acts like crystalloid.
@Science-Club crystalloid are the substance which can be crystallised easily from their aqueous soln and have size less than colloids
AS u can see that difference in ranks of letters above is either 2 or -2
SO in the given options the same pattern is followed by option 1
hence ans is option .
hope u understand.
@Ishitta-U as the direction of radial velocity changes during its motion the linear momentum does not remain conserved
but angular momentum is conserved
@Nishant-Thakre then I think ans given is wrong
4th option is the answer..
but I'm getting 3rd option as the answer..
hope u understand it
@Chemistry it's due to angle strain as the ring is small
@Chemistry grignard reagents are soluble in ether
