Question

What chemical is the most similar chemical to water, and why?

Answer 1

Isn't it that fake hydrogen thing, deuterium, \(D_2O\)

Answer 2

i would say that deuterium oxide is chemically identical to hydrogen oxide

Answer 3

I'm confused. Meep

Answer 4

I mean generally similar,
so you can use whatever similarities you think are most important

(im not looking for one answer)
im looking for lots of interesting answers with good justification

Answer 5

H2S having similar structure of water :)
https://en.wikipedia.org/wiki/Hydrogen_sulfide

Answer 6

SeH2 is also looks like same.
i am saying its based on structure similarities
https://en.wikipedia.org/wiki/Hydrogen_selenide

Answer 7

this another one https://en.wikipedia.org/wiki/Hydrogen_telluride

Answer 8

There's also other molecules like acids that look like water. Lol

Answer 9

that's a good start

Answer 10

Basically you're naming anything with same point group, \(C_{2v}\) @chmvijay

Answer 11

thank you @UnkleRhaukus interms of symmetry u can think of any ben molecules like SO2 etc :)

Answer 12

yaa you are right @abb0t

Answer 13

\(\huge C_{2v}\)

Answer 14

what is \(C_{2v}\) ?

Answer 15

Point group*

Answer 16

Auto correct on my tablet sucks.

Answer 17

Relates structures with similar structures are assigned a point group, in the case of water it's yeah, \(C_{2v}\) and as chmvajay said earlier those molecules also exhibit same point group. But doesn't mean they behave the same.just structurally the same.

Answer 18

perhaps you would like to go into some more detail @abb0t , ,

Answer 19

how about these O2F
http://en.wikipedia.org/wiki/Oxygen_difluoride
OCl2
http://en.wikipedia.org/wiki/Dichlorine_monoxide

Answer 20

I would but I don't think I can draw on my tablet...but I really would. I will try and explain best I can in short sentence...
