Do you know what a dative covalent bond is?

Yeh but I can’t figure out how to show it for nh4cl

Mmmmmm actually I’m not too sure either sorry😅I would have thought there’s single bond throughout the whole thing

the question doesn't ask for you to draw out the shape, it's just wanting you to explain what a dative covalent bond is and relate it to NH4Cl : ))

if a question does ever ask for you to draw out the shape, you indicate a dative covalent bond by an arrow pointing from the atom donating the electrons to the atom it's being donated to

Oooo I think if one of the surrounding atoms is an ion that would work out

there is a dative covalent bond in nh4+ but nh4cl as a whole molecule is ionic because the bonding between nh4+ and cl-


hopefully that makes more sense

Is it possible if you could draw it out?
R u saying that N donates both electrons to one of the + hydrogens? If so I get that but the cl- is confusing me. Does cl have an extra electron?

so basically the nitrogen atom in nh3 donates an electron to a hydrogen atom hence forming a dative covalent bond
this leads to that hydrogen atom transferring one of its electrons to chlorine which forms an ionic bond
