Question

Find odd man out
1 Aluminum 2 Nickel
3 Methane 3 Helium

Answer 1

helium is a inert gas ...

Al Ni and CH4 are not

but if we think in different way ie.

CH4 is a compound but in the case of He Al Ni they are elements ....

but i guess the second option is more appropriate because inert gases are basically stable because their valency is filled in the case of CH4 the valency is filled by covalent bond and is therefore stable therefore the first case is not somewhat applicable therefore the second one is right

ie.

ANSWER:- CH4 IS THE OD ONE

hope it help....

plzz merk me as brainliest....

Answer 2

methane (as other three are elements while methane is a compound)
