What in a molecule influences the way that a molecule reacts?

The reactivity of a molecule is often affected by the degree of substitution of the carbon bonded to a functional group; the carbon is designated as primary, secondary, or tertiary.

How do functional groups affect the properties of molecules?

Functional groups are important in chemistry because they are the portion of a molecule that is capable of characteristic reactions. They, therefore, determine the properties and chemistry of many organic compounds. A functional group gives an organic compound a property that is different than it would otherwise have.

How do functional groups affect reactivity?

Functional groups play a significant role in directing and controlling organic reactions. Alkyl chains are often nonreactive, and the direction of site-specific reactions is difficult; unsaturated alkyl chains with the presence of functional groups allow for higher reactivity and specificity.

What is the third member of alkyne series?

The third member of this family is HC≡C−H2C−H2C−CH=CH2 which is C6H8. Hence, C is the correct option. Note: The number of double bonds in alkenes should be at least one and the number of triple bonds in alkynes should be at least one.

What is the molecular formula of 2nd and 3rd member of homologous series?

Ethene is a member of alkene series. Alkenes are the group of compounds having double bond. The general formula of alkene is CnH2n. The second and third member have the formula C3H6 and C4H8.

Which of the following is third homologue of aldehyde homologous series?

Propionaldehyde

Which of the following is not a member of homologous series?

All are alkenes except 2-butyne. So, 2-butyne does not form the member of homologous series.

What is meant by homologous series?

Let’s see the definition of homologous series: > A homologous series is a series of hydrocarbons which have similar chemical properties and they share the same general formula. They are organic compounds having similar structure and functional groups.

Which of the following are members of same homologous series?

CH3OH,C2H5OH,C3H7OH are the member of the same homologous series as they all contain same basic structure and the difference in each case is -CH2- group.

What is not true about homologous series?

Homologous series differ by a CH2 group. As the molecular mass increases in a homologous series, a gradation in physical properties is observed.

Do homologous series have same physical properties?

The chemical properties of homologous series are similar because they have the same functional group. However, the physical properties of homologues are different because of increased London dispersion forces. Other molecules besides organic compounds can have homologous series as well.

What is homologous series Class 10?

Homologous Series. Homologous Series. A series of carbon compounds in which same functional group substitutes the hydrogen atom is called a homologous series. These compounds have similar chemical properties due to the addition of same kind of functional group throughout the chain.
