What is the basicity order of f..cl ...br ..and i?

this you asking na??

yes

See more the strength of acid weak is its conjugate base..So HI is most acidic so I- is least basic...means F- Is more basic

In down the group the size of the atom dominances over EN factor

yes sir

got it??

please accept the answer if you got it😊

yes

Best regards 😊👍

sir I m just asking top to bottom size increases na so basicity top to bottom decreases

it's incomplete question

but F is more electro negative na so how can it have greater basic characteristics

up to down in the periodic table acidity increase because size increase so basicity decrease

but this case applied in the case of p block hydrides

yes sir I m confused little bit where to use what but know l m clear

if the basicity asking in same period of element like C.. N..O..F then the basicity is inversely proportional to e.n

inversely proportional to zeff

left to right, basicity also decrease

.Zeff means sir

and when basicity asked in diff periods then used the size rule top to bottom ..the basicity is inversely proportional to the size

The effective nuclear charge is the net positive charge experienced by an electron in a polyelectronic atom. 

yes sir

yew, simun

just remember that left to right and down the group, in both the case basicity decrease

check it

yes sir tq sir for clearing this 😊😊🙏🙏
