Provide a structure for the compound with molecular formula C9H9ClO and with the following spectroscopic data. IR: 1680 cm-1 1H NMR: 3.5δ (triplet, I=2H), 4.0δ (triplet, I=2H), 7.4δ (triplet, I=2H), 7.6δ (triplet, I=1H), 7.9δ (doublet, I=2H)

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?  

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Idon't know hope someone you

Answer the same molecular formula;
