1. It is cis-trans pair (no chiral carbon atom so no optical isomerism)

2. has chiral carbon atom so case of optical isomerism, mirror images so dextro and laevo

can anyone explain to me how to write the structures of some organic compounds like but-2-ol?

name is not correct

IUPAC name has four part

Extra Group................Main Chain............Bond Name..............Main Group

so name may be

*****..........................but........................an...................................2ol

****** means no extra group is present 

Main group is alcohol and its name is ol, 2 for second place in chain

"but" for 4 carbon and "an" for all single bond

so structure will be     CH3CH(OH)CH2CH3

Boron is  a chemical element produced by cosmic ray spallation. Chemically uncombined Boron which is classified as a metalloid is not found naturally on earth. Several allotropes of Boron exist. Natural Boron is composed of two stable isotopes one of which is Boron 10, used as a neutron capturing agent.
