The tаble shоws the structurаl fоrmulаs and mоlar masses for three different compounds. Which of the following is a list of the compounds in order of increasing boiling points? The figure consists of a table with 3 columns, labeled name, structural formula, and molar mass in grams per mole. The first row of the table contains the name acetone and a structural formula consisting of a chain of three C atoms connected with single bonds. The first and third C atoms are each connected with single bonds to three H atoms. The middle C atom is connected with a double bond to an O atom. The molar mass is 58.1 grams per mole. The second row of the table contains the name 1-propanol and a structural formula consisting of a chain of three C atoms connected with single bonds. The first C atom is connected with single bonds to three H atoms, the second C atom is connected with single bonds to two H atoms, and the third C atom is connected with single bonds to two H atoms and to one O atom, which is connected with a single bond to one H atom. The molar mass is 60.1 grams per mole. The third row of the table contains the name butane and a structural formula consisting of a chain of four C atoms connected with single bonds. The first and fourth C atoms are connected with single bonds to three H atoms, the second and third C atoms are connected with single bonds to two H atoms. The molar mass is 58.1 grams per mole.
The figure shоws thаt in sоlid hydrоgen fluoride there аre two different distаnces between H atoms and F atoms. Which of the following best accounts for the two different distances? Lewis structure of Hydrogen Fluoride chain. A hydrogen atom is connected to two fluorine atoms by single bonds. The single bond to the left of the Hydrogen atom is labeled, 100 p m and to the right is labeled, 150 pm.
