Question

Can anybody please help me with this?


Which of the following pairs of elements is least likely to be held together by a covalent bond?

A. O and C

B. O and N

C. Mg and O

D. O and Cl

Answer 1

A. O & C

Answer 2

Can you please explain?

Answer 3

if the electronegativity differences between those atoms is less than 1.7 between the two elements then the bond is more covalent in nature

Answer 4

So A is the correct answer?

Answer 5

least likely to be held together by a covalent bond? try to understand this mean which is not a covalent in this they are asking

Answer 6

electronetavity of O = 3.5 for C its = 2.5
for N it is = 3.0
for Cl it is =3.0
for mg =1.2
can u find the difference between their electronegativity
for example
O and C =3.5-2.5 =1<1.6 its covalent
like this do for the rest

Answer 7

RH are u getting it or No?

Answer 8

Yes I am, and Mg and O is the correct answer right?

Answer 9

yup :)

Answer 10

Thanks!

Answer 11

u r welcome
