Is the compositional (molecular) formula for a straight-chain alkene the same as for a straight chain alkane? Explain briefly.
What type of alkane matches, in molecular formula, an alkene. Give a specific example (for a particular alkane and a particular alkene -- but not involving 1-pentene. Example, here, means structures -- and structures mean: all atoms, all bonds, always).
An unknown metal hypochlorite salt, M(ClO)2, is subjected to analysis by iodometric titration: the salt is dissolved in dilute sulfuric acid, treated with excess aqueous KI, and then titrated with Na2S2O2 in the same manner as in your experiment
