Chemistry question? | Socratic (2024)

a) Lewis structure

You put the two #"O"# atoms in the centre, add an #"H"# atom to each #"O"#, distribute the 14 valence electrons to get the Lewis structure.

b) The weakest bond

The weakest bond in hydrogen peroxide is the #"O-O"# bond.

c) Longest wavelength to break the #"O-O"# bond

#"HO-OH" → "HO·" + "·OH"; ΔH = "142 kJ·mol"^"-1"#

This is the energy for 1 mol of molecules.

For 1 molecule,

#E = "142 000 J"/(1 color(red)(cancel(color(black)("mol")))) × (1 color(red)(cancel(color(black)("mol"))))/(6.022 × 10^23 "molecules") = 2.358 × 19^"-19"color(white)(l) "J"#

#E = (hc)/λ#, so

#λ = (hc)/E = (6.626 × 10^"-34" color(red)(cancel(color(black)("J·s"))) ×2.998 × 10^8 "m"·color(red)(cancel(color(black)("s"^"-1"))))/(2.358 × 19^"-19" color(red)(cancel(color(black)("J")))) = 8.42 × 10^"-7"color(white)(l) "m" = "842 nm"#

The longest wavelength that will break the #"O-O"# bond is 842 nm.
