2nd ..is incorrect evn pure water is a weak elctrolyte .....
Kw=10^(-14)
slightly ionises .......
3rd correct
4th incorrect .....ionic bond transfer of eltron .covalent bond sharing .... of eltrons
1then may be u are correct , lets ask ankit to give the answer ,
ankit plz tell wats the answer
1Arrey Amit i've read statement c many times in many standard books....and also i've solved a sum in which no. of ions in pure water were to be calculated...!!!
1chemical bond formation takes place when two unstable atoms interact by exchange or sharing of electrons to attain stability and not when force of attraction overcomes forces of repulsion
1hey.. guyz.. ll questions wit multiple ans be asked in aieee???
1in formation of co-valent bond electrons are shared not transfered
1At least we can be sure dat c is 100% correct as its single ans crrct ques!
