Concept explainers
Interpretation:
To give the number of hydrogen atoms bonded to each carbon atom in the substance given, and to write its molecular formula.
Concept introduction:
In skeletal structures the carbon atoms are not usually shown. Instead a carbon is assumed to be at each intersection of two lines and at the end of each line. The hydrogen atoms bonded to carbons are also not shown. The correct number of hydrogen atoms for each carbon atom is assigned keeping in mind that carbon has a valence of 4. The end of a line represents a carbon atom with three hydrogen atoms, CH3; a two-way intersection is a carbon atom with two hydrogen atoms, CH2; a three way intersection is a carbon with one hydrogen, CH; a four way intersection is a carbon with no attached hydrogen. Atoms other than carbon and hydrogen are shown. The molecular formula can be obtained by counting the number of atoms of different elements present in the molecule.
To determine:
The number of hydrogen atoms bonded to each carbon atom in the substance given and to write its molecular formula.
Interpretation:
To give the number of hydrogen atoms bonded to each carbon atom in the substances given, and to write the molecular formula.

- 2) (4 pt) After the reaction was completed, the student collected the following data. Crude product data is the data collected after the reaction is finished, but before the product is purified. "Pure" product data is the data collected after attempted purification using recrystallization. Student B's data: Crude product data "Pure" product data after recrystallization Crude mass: 0.93 g grey solid Crude mp: 96-106 °C Crude % yield: Pure mass: 0.39 g white solid Pure mp: 111-113 °C Pure % yield: a) Calculate the crude and pure percent yields for the student's reaction. b) Summarize what is indicated by the crude and pure melting points.arrow_forwardDon't used hand raitingarrow_forwardDon't used hand raitingarrow_forward
