For them to rhyme, you �d have to�pronounce the final �ence � in difference the same way you do for for hence.�You can force it as an artistic contrivance (as was often done in Elizabethan poetry, for example), but it would not sound like natural English to the majority of native speakers.

hence: hɛns
�
difference:��ˈdɪf(ə)r(ə)ns
�
The Wikipedia entry for rhyme is very good at describing all the different�understandings of what constitutes a rhyme
�
Daria, to�me neither �chance��(tʃɑːns) nor �glance� (ɡlɑːns) would rhyme with� �hence��(hɛns)
Some words that may rhyme with hence, depending on your accent, would be sense, cents,�pence, tense, tents, fence
