Question

what is the electrical interaction (IFA notation) for the natural phenomenon listed below.

1. turpentine is used to dilute an oil-based paint

2. melted ice dissolves into alcohol (CH3-CH2-OH) in a shot glass

3. food cooked on a teflon-coated pan doesnt stick

Exercise: Intermolecular Forces of Attraction (IFA) purpose of this exercise is to gain familiarity with the five general types ractions discussed in class. These are summarized in the table below. Electrical Interaction (IFA) Short-hand Notati Ion - Dipole ' Ion - d Dipole - Dipole d-d Dipole - Induced Dipole did Induced Dipole - Induced Dipole id-id Hydrogen Bonding H-bond Use your personal experience with everyday substances and your molecular ins class to determine the nature of the electrical interaction (IFA) responsible for t physical property described in each case below. The electrical interaction may favorable or unfavorable in each case as observed from its behavior. ctrical Interaction (IFA Notation) Description of natural phenomenon.

Answer 1

1. Turpentine is non polar and so it will be have id-id interaction with oils (non polar)

2. Ice when melts will dissolve alcohol because of the H-bonding.

3. Non stick pans have coating of teflon, which is carbon chain in which each carbon has two fluorine atoms, now fluorine has three lone pair of electrons and these lone pair of electrons repel the food, which is mostly containg nitrogen or oxygen which also have lone pair of electron. these can be thought of van der Waal interactions
