  Paired valence electrons forming covalent bonds in molecues are confined
cooper pair correlations. High pressure dissociates molecules in solid H2S,
SiH4, H2 etc. and form extended structures. However, valence electrons are
resilient and continue to bond and sometimes resonate. It is suggested that
some structures contain emergent Mott insulators (EMI) and support
superconductivity and other phases, under special conditions. In pressurized
solid H2S, we propose presence of a sublattice of relatively narrow, nearly
half filled band of H atoms, trapped in ordered interstitials of colvalently
bonded S atom network. EMI offers a high pairing energy scale. A theory for
recently claimed superconductivity in solid \hsm (Tc ~ 205 K), Silane (Tc ~ 17
K$), and systems like H2 is presented.
