Anthracene is a polycyclic aromatic hydrocarbon with chemical formula C₁₄H₁₀. The number of fused rings in Anthracene are three in number. This compound is colorful and is used in the formation of different dyes due to its property of deloclization of pi electrons. All the carbon atoms in Anthracene are sp² hybridized with a trigonal planar structure hence, the Anthracene is planar in nature.
Number of Sigma Bonds:
There are 26 sigma bonds (colored in Blue) in Anthracene among which 10 sigma bonds are between carbon and hydrogen atoms while the remaining are between the carbon atoms.
Number of Pi-Bonds:
There are 7 pi bonds in Anthracene (colored in red). All pi bonds are present between carbon and carbon atoms.
Number of Electrons in Sigma Bonds:
As one sigma bond is formed by 2 electrons hence, 26 sigma bonds will be formed by 52 electrons.
Number of Electrons in Pi Bonds:
As one pi bond is formed by the side wise overlap of two p orbitals hence one pi bond is formed by two electrons so, 7 pi bonds will be formed by 14 electrons.

In a mixture, we can separate the elements or compounds inside easily by using physical methods, such as filtration, evaporation, distillation etc.
However, a compund is two or more elements chemically combined together, so we cannot separate them using physical methods, only with checmicals methods such as apply heat or electricity (electrolysis)
Answer:
The correct order of increasing vapor pressure: Z,Y,X
Explanation:
It is given that the normal boiling point order of three liquids is:
Normal Boiling point is defined as the temperature at which the vapor pressure becomes equal to the atmospheric pressure.
Vapor pressure is the pressure exerted by vapor on the surface of liquid.Hence it increases with tendency of vapor formation.
High boiling point implies that high energy is required to convert the liquid into vapor state and hence the vapor pressure reaches atmospheric pressure at higher temperatures.
Low boiling point implies that the liquid gets easily boiled at a low temperature and converts into vapor with ease and hence exert high vapor pressure.
Bottom line is vapor pressure decreases as boiling point increases at STP.
Hence the order of increasing vapor pressure is Z,Y,X
