Increasing order of basicity:
furan, thiophene, and pyrrole?

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   

Are there any options that could alot..

Qand k are only the same when the forward rate of the reaction has reached zero.
