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.

- What is the mass of the molecular ion formed from compounds having molecular formula C5H10arrow_forwardA colorless, viscous liquid, has a molar mass of 90. g/mol. Elemental analysis shows that this compound is 40.0 % carbon, 6.71% hydrogen, and the rest is oxygen. Determine the molecular formula of the compound in C-H-O order. For example, the formula C2H6O would be entered as C2H6O or C2H6O1.arrow_forwardThe following chemical structure represents a molecule of what molecular formula?

- Which of the formulas must be molecular formulas? HO H2O2 C6H12O6 CH2O C3H4O3arrow_forwardTRUE OR FALSE All atoms play a role in the physicochemical and pharmacologic properties of a molecule. Sophistication and advancement in technology are the main driving forces of drug development. Organic medicinal chemistry is the study of matter, specifically, all carbon-containing compounds. A functional group will always have the same physicochemical properties, regardless of its neighboring atoms in a molecular structure. Addition of a single methyl group in a drug molecule may result to changes in physical, chemical, pharmacokinetic, and pharmacologic properties. Steric effects occur when bulky and large functional groups are near each other in a molecular structure. Molecules that are highly capable of hydrogen bonding tend to be more soluble in nonpolar solvents.arrow_forward(11) Try Again Your answer is incorrect. • BP: The name of this compound is not "boron phosphide". Be sure you know the correct names of all elements in this compound. Check the Periodic Table if necessary. • C3S2: Your answer is incorrect. Fill in the systematic names of the following chemical compounds. Note: for compounds containing hydrogen, you may give the common name instead. molecular formula BP C₂S₂ CS₂ BI₂ H₂O Explanation Recheck name of compound boron phosphide carbon subsulfide carbon disulphide boron triiodide water X Ś olo Ararrow_forward
