Concept explainers
Interpretation:
The statement concerning alkyne properties is incorrect has to be chosen from the given options.
Concept Introduction:
Organic compounds are represented shortly by the molecular formula and structural formula. Each and every compound has its own molecular formula. Compounds can have same molecular formula but not same structural formula.
Regarding density, alkynes have density lower than water. When alkynes are mixed with water, two layers are formed which is a result of insolubility. Alkynes are present on top of water layer which is due to lesser density.
Boiling point of alkynes increase with an increase in carbon‑chain length. The alkynes with lower molecular mass are gases at room temperature.
Alkynes undergo combustion reaction to give carbon dioxide and water as product.

What would be the molecular formula for a polymer made by linking ten glucose molecules together by dehydration reactions? Group of answer choices A. C60H120O60 B. C60H102O51 C. C60H100O50 D. C60H111O51 Use the following information to answer the following questions."The native structure of hemoglobin (HB) comprises of two α and two β subunits, each of which carries a heme group. There appear to be no previous studies that report the in-vitro folding and assembly of Hb from highly unfolded α and β globin in a 'one-pot' reaction. One difficulty that has to be overcome for studies of this kind is the tendency of Hb to aggregate during refolding. This work demonstrates that denaturation of Hb in 40% acetonitrile at pH 10.0 is reversible."
