I have couple questions on orgo:

1. does this compound participate in H-bonding? PhocHCH2...as far as I know this is ether and ether does not participate in H-bonding.

2.Definition of Syn addition and Anti addition. are these same as Cis and trans??

Thanks

1) you are missing an H somewhere but correct there is no H-bonding in an ether.

2)Syn is where the two substituents being added are coming from the same side while anti means that one attacks from the top say and the other attacks from the bottom. This applies by alkynes as well as alkanes.
Cis Trans has to do with the makeup of the molecule but isnt describing a partuicular addition of any kind.

Aziz. i am doing right now the test about that. it was confusing for me too.
the answer is yes and no, they can not have intermolecular H bond. but they can have H bond in water.
about second question when you have a plate(double bonds or aromatic compond) you have two sides when two groups attack same side it is going to be syn and make cis but one group comes from one side of the plate and another on from other side will be anti and you are going to have anti. hopefuly this explanation helped.
