True rhymes with peroxide share its stressed /ˈɑk/ syllable plus /ˌsaɪd/: oxide /ˈɑkˌsaɪd/, dioxide /daɪˈɑkˌsaɪd/, and monoxide /məˈnɑkˌsaɪd/. Words like side, slide, and bride match only the final /saɪd/ sound, not the stressed vowel, so they are not exact rhymes. Beware the -ide spelling: it is pronounced /aɪd/ (as in chloride /ˈklɔːr.aɪd/), never /ɪd/, and the stress can shift between similar forms.
