Answer the following question given this paragraph: molecular masses. Primary amines tend to have boiling points intermediate between those of the corresponding alcohol and alkane. Moreover, secondary and tertiary amines have lower boiling points than primary amines of comparable molecular mass. Tertiary amines form cations analogous to the ammonium ion (NH 4+), in which all four H atoms are replaced by alkyl groups. Such substances, calledquaternary ammonium salts, can be chiral if all four substituents are different. (Amines with three different substituents are also chiral because the lone pair of electrons represents a fourth substituent. ) Alkylamines can be prepared by nucleophilic substitution reactions of alkyl halides with ammonia or other amines: Equation 24.12. Q: Which reaction between alkyl halides and ammonia makes alkylamines? A:
OPTIONS:
- nitrogen catabolism
- conductive substitution reactions
- nucleophobic reactions
- nucleophilic substitution reactions

Answer: nucleophilic substitution reactions

Question: Answer the following question given this paragraph: A snowflake is made of ice, or water in the solid state. A solid is one of four well-known states of matter. The other three states are liquid, gas, and plasma. Compared with these other states of matter, solids have particles that are much more tightly packed together. The particles are held rigidly in place by all the other particles around them so they can't slip past one another or move apart. This gives solids a fixed shape and a fixed volume. Q: What state of matter completes the list: solid, liquid, gas? A:
OPTIONS:
- energy
- ice
- power
- plasma
Answer: plasma

input with options: Answer the following question given this paragraph: Halide minerals are salts. They form when salt water evaporates. This mineral class includes more than just table salt. Halide minerals may contain the elements fluorine, chlorine, bromine, or iodine. Some halide minerals combine with metal elements. Common table salt is a halide mineral that contains the elements chlorine and sodium. Fluorite is a type of halide that contains fluorine and calcium. Fluorite can be found in many colors. If you shine an ultraviolet light on fluorite, it will glow!. Q: What type of minerals form when salt water evaporates? A:
OPTIONS:
- sulfide
- carbonate
- fermite
- halide
output: halide

Q: Answer the following question given this paragraph: The Linnaean system of classification consists of a hierarchy of groupings, called taxa (singular, taxon). Taxa range from the kingdom to the species (see Figure below ). The kingdom is the largest and most inclusive grouping. It consists of organisms that share just a few basic similarities. Examples are the plant and animal kingdoms. The species is the smallest and most exclusive grouping. It consists of organisms that are similar enough to produce fertile offspring together. Closely related species are grouped together in a genus. Q: What do we call the system of classification consisting of a hierarchy of groupings called taxa? A:

OPTIONS:
- lamarckian system
- linchpin system
- crocodilian system
- linnaean system

A: linnaean system

input: OPTIONS:

Question: Answer the following question given this paragraph: Figure 16.19 Neurons contain organelles common to other cells, such as a nucleus and mitochondria. They also have more specialized structures, including dendrites and axons. Q: What contain organelles common to other cells, such as a nucleus and mitochondria, and also have more specialized structures, including dendrites and axons? A:
OPTIONS:
- follicles
- blood cells
- muscle cells
- neurons
Answer:
neurons
