Is 4-isopropyl-2,5-dimethyl-2-hexene chiral?

             No, 4-isopropyl-2,5-dimethyl-2-hexene is not chiral.

                    Chiral compounds are those compounds which contains atleast one chiral carbon. Chiral carbon is that carbon to which all the four attached atoms or group of atoms are different inn nature on the basis of their atomic or molecular mass.

Examples of Chiral compounds are;

                                  1) 1-bromo-1-fluoro-1-iodoethane

                                  2) chlorofluoroiodomethane

                                  3) 2-fluorobutane

The structure of 4-isopropyl-2,5-dimethyl-2-hexene is attached below. As the structure doesn't contain any stereo-center therefore this compound is not chiral in nature.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

i believe the answer is true.
