130 Questions and 100% Verified Correct
Answers with Rationale Guaranteed A+
alcohol - CORRECT ANSWER: ∙contains an -OH (hydroxyl) group
∙suffix "-ol"
∙polarity= very
∙h-bonding
aldehyde - CORRECT ANSWER: ∙has a carbonyl C atom bonded to a lone H atom
∙suffix "-al"
∙polarity= somewhat
∙dipole
Alkane - CORRECT ANSWER: ∙hydrocarbon in which the carbon atoms are connected
only by single bonds
∙prefix representing # of carbons in continuous chain and the suffix "-ane"
Alkene - CORRECT ANSWER: ∙hydrocarbon with at least one c=c double bond
∙suffix "-ene"
∙polarity= non
∙dispersion forces
alkyne - CORRECT ANSWER: ∙hydrocarbon with at least one c to c triple bond
∙suffix "-yne"
∙polarity= non
∙dispersion forces
,Alpha particle - CORRECT ANSWER: ∙He nucleus
∙2 protons + 2 neutrons
∙mass # of 4, atomic # of 2, charge of 2+
∙very low penetration
∙a lot of damage to surface cells
amide - CORRECT ANSWER: ∙compound with a carbonyl group attached to a N atom
∙suffix "-amide"
∙polarity= somewhat
∙dipole
amine - CORRECT ANSWER: ∙compound where a N atom is attached to one or more C
atoms
∙suffix "-ylamine"
∙polarity= very
∙h-bonding
amino acid properties - CORRECT ANSWER: ∙an ammonium group (-NH₃⁺)
∙a carboxylate group (-COO⁻)
∙essential amino acids cannot be synthesized in the body; they must be consumed
Amphoteric - CORRECT ANSWER: substance that can act as both an acid and a base
atomic radius - CORRECT ANSWER: ∙as you go down a column the radius
INCREASES SIGNIFICANTLY
∙as you go across a row the radius DECREASES SLIGHTLY
, beta particle - CORRECT ANSWER: ∙high energy electron
∙mass # of 0, atomic # of -1, charge of 1-
∙fairly low penetration
∙moderate damage over a small depth
biological effects of radiation - CORRECT ANSWER: ∙when radiation hits molecules,
electrons are knocked loose "ionizing radiation"
∙ions are extremely reactive and cause damage to living cells
∙cancer cells are extra reactive to radiation
∙radiation can also cause cancer, tumors, anemia, and mutations in healthy cells
Bronsted-Lowry - CORRECT ANSWER: Acid: compound that can donate H+
Base: compound that can accept H+
carbohydrates - CORRECT ANSWER: ∙all made of carbon, hydrogen, and oxygen
∙one form of energy storage
carboxylic acid - CORRECT ANSWER: ∙has a carbonyl C atom bonded to a -OH group
∙suffix "-oic acid"
∙polarity= very
∙h-bonding
chemical change - CORRECT ANSWER: conversion of a substance into different
substance (ex: rusting iron)
Cis v trans fatty acids - CORRECT ANSWER: Cis= larger atoms on a double bond are
on the same side of the bond
trans= larger atoms on a double bond are on opposite sides
