Treatment of isobutene [(CH3)2C=CH2] with (CH3)3CLi forms a carbanion
that reacts with CH2=O to form H after water is added to the reaction
mixture. H has a molecular ion in its mass spectrum at m/z = 86, and
shows fragments at 71 and 68. H exhibits absorptions in its IR spectrum
at 3600−3200 and 1651 cm−1, and has the 1H NMR spectrum given below.
