hydrocarbons

During a chemistry class, Ayesha and Minahil were discussing how two or more compounds can have the same chemical formula but different structural formulas. What are these compounds called?

• Isomers

• Isotopes

• Polymers

• Allotropes

Hamda and Ayesha are comparing their new toys. Identify what’s same in these structures.

• Shape

• Color

• Size

• Material

What are the two main categories of organic compounds?

Irum and Ayesha are discussing the structure of molecules in their chemistry class. Irum asks, "What type of hybridization is present in singly bonded carbon atoms in saturated hydrocarbons?"

• The hybridization present in singly bonded carbon atoms in saturated hydrocarbons is sp3 hybridization.

• The hybridization present in singly bonded carbon atoms in saturated hydrocarbons is sp2 hybridization.

• The hybridization present in singly bonded carbon atoms in saturated hydrocarbons is sp hybridization.

• The hybridization present in singly bonded carbon atoms in saturated hydrocarbons is dsp3 hybridization.

Irum and Ayesha are in a chemistry lab, and they are asked to identify an alicyclic hydrocarbon from a set of samples. Which of the following is an alicyclic hydrocarbon?

• Cyclobutane

• Benzene

• Ethylene

• Methane

Fatima and Javeria are studying chemistry and they come across a topic about hydrocarbons. Hydrocarbons are defined as:

• Compounds made entirely of hydrogen and carbon atoms

• Compounds made of hydrogen, carbon, and oxygen atoms

• Compounds made of hydrogen, carbon, and nitrogen atoms

• Compounds made of hydrogen, carbon, and sulfur atoms

Minahil and Ayesha are discussing the structure of hydrocarbons in their chemistry class. Minahil says that acyclic hydrocarbons contain open chains of carbon atoms, while cyclic hydrocarbons contain closed rings of carbon atoms. Ayesha disagrees. Who is correct?

• Minahil is correct.

• Ayesha is correct.

• Both are incorrect.

• Both are correct.
