Iam confused what is being asked, can someone give an explanation to what is being asked? part of the reasoning that led van't hoff and le bel to propose a tetrahedral shape for methane, ch4, was based on the number of compounds that are theoretically possible for substituted methanes; that is, compounds in which one or more hydrogens have been replaced by some other group. for example, only one compound of the type ch2x2 has ever been found. is this consistent with a tetrahedral shape? with a square planar shape? provide an explanation for each answer using appropriate diagrams.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
